Primitive filtering helpers.

The crate intentionally keeps filtering narrow: a causal moving average plus first-order low-pass and high-pass filters.

Examples

use use_simple_filter::{first_order_low_pass, moving_average_filter};

assert_eq!(moving_average_filter(&[1.0, 3.0, 5.0], 2).unwrap(), vec![1.0, 2.0, 4.0]);
assert_eq!(first_order_low_pass(&[0.0, 1.0, 1.0], 0.5).unwrap(), vec![0.0, 0.5, 0.75]);
